Which statements describe the six elements found in all living things? Check all that apply.
vovangra [49]

Answer:

Carbon is the basis of all living things

Nitrogen is found in certain foods

Oxygen and hydrogen combine with each other to form water

Carbon, oxygen, hydrogen, nitrogen, phosphorus and sulfur are found in organic compounds

Explanation:

We are all made up of mainly three elements, Carbon, Hydrogen, and Oxygen. These three elements are found in every living organism on our planet, and along with a few trace elements, they make up all the nutrients we take in and use to build our bodies and survive.

Nitrogen is primarily found in meats, and this is because nitrogen is a key element in amino acids (which are used to build proteins), however we cannot directly assimilate nitrogen from the air, so we have to assimilate it through amino acids already synthesized in plants, or in proteins found in meat.

The chemical formula for water is H₂O. Seeing the chemical formula, it is obvious that hydrogen and oxygen are the only elements in the water molecule.

In our bodies, we use phosphorus to form our skeleton and help maintain it, sulfur and nitrogen can be found in some amino acids, and carbon, hydrogen and oxygen can be found in carbohydrates, lipids and proteins.

How do I find the moles of OH- which reacted (mol) in the titration. Table Attached
BaLLatris [955]

Answer:

It is equal to the number of moles of acid that reacted. When Oxalic acid is your limiting reactant it is the # of moles of oxalic acid used. When NaOH is your limiting reactant it is equal to the number of moles of NaOH used.

Five calcite, CaCO3 (MM 100.085 g/mol), samples of equal mass have a total mass of 12.2±0.1 g . What is the average mass and abs
Westkost [7]

Answer:

  • <em>The average mass of calcium in each sample is: </em><u>0.978 g</u>

<em />

  • <em>The absolute uncertainty is: </em><u>0.008 g</u>

Explanation:

The <em>absolute uncertainty </em>of the total samples indicated in the statement is ± 0.1 g.

When you multiply or divide quantities with uncertainties, you calculate the final uncertanty by adding the <em>relative uncertainties</em> together.

The relative uncertainty is the absolute uncertainty divided by the quantity:

  • Relative uncertainty = 0.1g / 12.2 g = 0.008

The average mass of calcium is calculated using proportions, along with the molar masses:

  • Molar mass of calcium: 40.078 g/ mol (from a periodic table)

  • Molar mass of calcite: 100.085 g/mol (given)

Proportion:

  • 40.078 g of calcium / 100.085 g of calcite = x / 12.2 g of calcite

  • x = 12.2 × 40.078 / 100.085 g = 4.89 g calcium

So the total mass of calcium in the five samples is 4.89 g, and the average mass in each sample is:

  • Average mass = total mass of five samples / number of samples

  • Average mass = 4.89 g / 5 = <u>0.978 g of calcium</u>

So, the first answer is that the average mass of calcium in each sample is 0.978 g ( keep 3 signficant figures, such as the quntitiy 12.2 shows, as  you have only used multiplication and division).

The absolute uncertainty of each sample is the relative uncertainty multiplied by the average mass of calcium of the five samples, rounded to one decimal:

  • Absolute uncertainty = 0.978 g × 0.008 ≈ 0.008 g

The answer to the secon question is that the absolute uncertaingy of calcium in each sample is 0.008 g.
